I: CHECKROW PLANTER ATTACHMENT.

Application filed November 19, 1926.

This invention relates to check row attachments especially adapted to be used in conjunction with corn planters of standard form and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide an attachment of simple and durable structure which may be easily and quickly applied to the frame of the planter and which may be readily adjusted in order to accurately and precisely vary the distance between the hills in which the grain is deposibed in the soil.

A further object of the invention is to provide a truck means for lifting the planter when a turn is being made and for supporting the planter in an elevated position when the same is being moved over a roadway or from field to field A still further object of theinvention is to provide means for actuating the shaft which operateslthe seed dropping valve of the planter, the said means including the usual arm attached to the said shaft but inclined downwardly and rearwardly and having its free end disposed in.the path of movement of a series of buttons mounted in spaced relation upon an endless chain and which is trained around a sprocket wheel mounted upon the axle of the planter and sprocket fwheels disposed one above the other, in spaced relation and located at the intermediate portion of the frame of the planter. The arrangement of the last mentioned sprocket wheels is such that the chain isprovided with a vertical run which passes transverselyof the free end of the arm and when thebutton comes in contact with the arm the same is rocked whereby the shaft is turned and the seed valves are operated.

A further object of the invention is to provide means for positively connecting the ground engaging wheels ofthe lanter with axle thereof in Order that t iere may be no relative play between the axle and the frame of the planter and in order that rotary movement may be positively transmitted from the axle of the planter to the chain and sprocket wheels of the attachment in order that there will be no loss of motion which might tend to cause the check row alinement of the planting to become i1"- re lar or uneven. Also means are provi ed for positively preventing the ground Serial No. 149,311.

engaging wheels from slipping with relation to the surface of the soil. Y

A further object of the invention is to provide an attachment of the character stated in which all of the parts are mounted directly upon the frame ofthe planter and consequently when the frame is raised or lowered the chain will remain at the same degree of tension. Also the major portion of the weight is disposed toward the rear of the planter frame and this will causethe assuring the proper planting of the seed at accurately spaced distances apart.

In the accompanying drawings:- Figure 1 is a top plan view ofaplanter with the attachment applied thereto.-

Figure 2is a side elevational view of the same. 1

Figure 4 is a fragmentary longitudinal sectional view of the same cut on the line 4 -4 of Figure 1.

Figure 5 is a perspective view of a bracket used in the attachment.

Figure 6 is a fragmentary sectional view of the attachment cutonthe line 66 of Figure 4.

Figure 7 is a side elevational View of one of the spade lugs used upon the planter 3. Brackets 5 depend from the intermediate portion of the frame lfand a-hook lever 6 is pivoted between the said brackets.v The forward end of the snid leveris downward- 1y curved as at 7 and is pivotallyconnected with the forwardend ofa bar 8; which in whereby the bar 8 is moveddongitudinallys and the frame 9 is swung under the axle 2 whereby the wheels ldar' carried under the axle Q and therear portion of the frame 1 is elev'ated'thn's liftihgithe ground engaging Wheels 3 and the spade lugs 4 thereof above the aerated the ground. \Vhen' the .parts are in-this "position the planter .11] ay be readfily "turned "and the fraine is supported so that thdgrourid' engaging; Wheels I and the 'ipade lugsare held above the surface ofthe gr6und"when the planter is being moved ffromfield to-field.

A sprocket when llis mounted upon the axle 2 toone side of the median longitudinal dimension of the frame 1 and a sprocket chain 1-2is' trained around the sprocket'wheel 11 and also around-"a" sprocket wheel 13 r momiteau onia shaft 14;Which controls the .lj'otationfof the plate in the bottom of the seed hopper'lzi (not shown) and-in z'riusuel manner: The downwardly and rearwardly disposed mechanism-"of the planter? Aspi'ing 18 is connected at one end withthe arm 16 and at its other end with the frame 1 and is under tension with aftendeney tonorinally hold J the rear free endfofth'e' arm 16 inan elevated position. v v 7 1 A? relatively large sprocket Wheel 19 is mountednpon the axle am the opposite side of; thefmedianlongitudinal dimension of "the framed from that'side at which the sprocket wheel 11 is mounted. An endless sprocket 'chain 2O strained around thesprocket wheel 19 and isprovided at its side and atsp'aced intervals' witl outstanding buttons or pins Q13*The saidfchain'20 is alsotrained around upper and lower sprocket-wheels 22 and'23 "which arejournaled'at the intermediate portionpf the frame land the free end of the arm 16 lies in the path ot 'movement" of the pins or buttons 21. The wheels22 and 23 aire oarried by a bracket 24 whieh, isatt ached *tofith frame l otf the planter and which are looated 'atthesame side as that at which the sprocket wheel -19-i-isi located. "Thus the wveight 'ofthe-attachment is counterbalanced -by theaweight of tliesprocketwheels 11 and 13gand theiehain 12 and consequently: when the planter is iii-operation the tendency to side draft-Will be eliminated or prevented.
